Konus Medullaris ve Kauda Equina Sendromu
Özet
Lumbosakral ve koksigeal sinir köklerinin fonksiyon kaybıyla seyreden kauda equina sendromu (KES) ve konus medullaris sendromu (KMS), sıklıkla acil cerrahi müdahale gerektiren önemli tablolardır. Tanı konulabilmesi için mesane/bağırsak disfonksiyonu, sele tarzı duyu kusuru ya da alt ekstremitelerde nörolojik defisitle birlikte seksüel disfonksiyon bulgularından en az birinin bulunması şarttır. Hastalığın etiyolojisinde lomber disk herniasyonları, kırık veya subluksasyonla sonuçlanan travmalar, konjenital veya dejeneratif spinal stenoz, epandimom gibi primer spinal tümörler, enfeksiyonlar, toksik ve vasküler nedenler yer almaktadır. Tanı ve ayırıcı tanıda altın standart MR görüntülemedir; elektrodiyagnostik yöntemler ile BOS incelemeleri de hasar yerinin tespiti ve diskojenik olmayan nedenlerin ayrımında kritik rol oynar. Geri dönüşümlü bir neden saptandığında cerrahi dekompresyon uygulanmalıdır. Prognozun optimize edilmesi ve kalıcı nörolojik hasarların önlenmesi adına, semptom başlangıcından itibaren ilk 24 saat içinde acil cerrahi müdahale yapılması önerilmektedir; inkomplet vakalarda cerrahi sonrası prognoz çok daha yüz güldürücüdür.
Cauda equina syndrome (CES) and conus medullaris syndrome (CMS), which manifest as functional loss of the lumbosacral and coccygeal nerve roots, are critical conditions that frequently require emergency surgical intervention. For diagnosis, at least one of the following findings must be present: bladder/bowel dysfunction, saddle anesthesia, or sexual dysfunction accompanied by a possible neurological deficit in the lower extremities. The etiology includes lumbar disc herniations, traumas resulting in fractures or subluxation, congenital or degenerative spinal stenosis, primary spinal tumors such as ependymomas, infections, toxic, and vascular causes. MRI is the gold standard for diagnosis and differential diagnosis; electrodiagnostic methods and CSF examinations also play a critical role in identifying the lesion site and differentiating non-discogenic causes. Surgical decompression must be performed when a reversible cause is identified. To optimize prognosis and prevent permanent neurological damage, emergency surgical intervention is recommended within the first 24 hours of symptom onset; incomplete cases demonstrate a much more favorable prognosis after surgery.
